Now that Windows 10 has HTTP/2 support with IIS, I have decided to play with it.  It seems ideal to serve SPA modules over HTTP/2.  There is no longer a need to concatenate javascript files anymore by utilizing a javascript module loader like SystemJS.  It is more efficient to load on demand and cache reusable resources in finer grained chunks.  Bundling was only advantageous over HTTP/1.1 because of the large cost of opening up too many TCP requests, which HTTP/2 now circumvents.

I have discovered that IIS can only serve HTTP/2 requests through TLS, and thus DNN portals wishing to take advantage of the new protocol must be browsed to via HTTPS.  There seems to be a bunch of blocked resources on a clean install of DNN8 when browsed to over HTTPS.  They look to be a bunch of font files from jquery.js and Telerik.Web.UI.WebResource.axd.  See below for logs from Chrome's console.

These 'Mixed Content' errors appear even on an empty page with no modules.  I checked the CDN settings and they are all disabled.  Would anyone happen to know how to remedy this?  Missing font resources are unlikely to break anything critical.  But it is rather obnoxious to have all these errors flooding the browser console.  There are 12 of them!

I was using a clean install of DNN 8.0.1.  Seeing these errors on an empty page, using the default skin.  It is not too difficult to replicate.

On Windows 10, within IIS.  Simply create a self-signed certificate and add a new binding to a DNN8 website using the HTTPS type.  IIS on Windows 10 will automatically serve the site over HTTP/2 when browsed to via https:// URL.  Fortunately, there is no other configuration needed.  It just works ^_^
